Document Type and Number:
WIPO Patent Application WO2001091273
Kind Code:
A3
Abstract:
A DC/DC converter circuit includes an input capacitor (C11), an indicator (L11), a diode (D11), a transistor (T11) and a control circuit (18). The control circuit operates to control the transistor (T11). An output capacitor (C21) is connected between the output and the input of the circuit. Connection in this way usefully reduces the size of the output capacitor.
